How to Increase PHP Time Limit for a WordPress Site?

The PHP Time Limit is the amount of time that your site will spend on a single operation before timing out. When an operation reaches the time limit set, then it will return a fatal error that looks like this:

Fatal error: Maximum execution time of xx seconds exceeded...

Method 1: Edit file .htaccess:

Add the following to .htaccess (Make sure you back up .htaccess before you edit it):

php_value max_execution_time 300

Method 2: Edit file wp-config.php:

Add the following to wp-config.php:

set_time_limit(3000);

Method 3: Editing php.ini
